# Este script SlackBuild descompacta o pacote Debian GBPCEFwr(64|32).deb usado
# no internet banking da CEF-Caixa Econômica Federal, e faz um pacote para ser
# instalado no Slackware 15.0 (versão estável) e Slackware -current (versão de
# desenvolvimento).
#
# Link para o Slackware 15.0:
# http://www.slackware.com/
#
# Link para o Slackware -current:
# https://slackware.nl/slackware/slackware-current-iso/
# https://slackware.nl/slackware/slackware64-current-iso/
# (novos isos são criados automaticamente quando há mudanças no ChangeLog,
#  as mudanças são quase sempre diárias
# https://ftp.osuosl.org/pub/slackware/slackware{64}-current/ChangeLog.txt)
#
# Para executar este script: o script deve estar no mesmo diretório que o
# pacote Debian GBPCEFwr(64|32).deb. O pacote de instalação será criado no
# diretório /tmp (default para $OUTPUT).

# on the right side marks the last column you can put a character in.  You must
# make exactly 11 lines for the formatting to be correct.  It's also
